LG Uplus announced on the 20th that it will verify the reliability of its self-developed AI model 'Ixigen' during the Mobile World Congress (MWC) 2025, the world's largest mobile communications exhibition, held in Barcelona, Spain, in early next month.

LG Uplus will participate in the 'Red Team Challenge,' a global telecommunications AI model safety and reliability verification competition hosted by the Global System for Mobile Communications Association (GSMA) at MWC25. The challenge involves 80 to 100 evaluators acting as hackers to identify AI biases, hallucinations, and other vulnerabilities. The vulnerabilities found by the evaluators are scored by a judging panel, but the number of participating companies and final rankings are not disclosed externally.

LG Uplus will participate in the challenge using Ixigen, a small language model independently developed based on 'ExaOne,' a large language model developed by LG AI Research. Ixigen is an AI model trained on telecommunications and platform data based on ExaOne, and LG Uplus applies it to various AI services such as network operation agents, chat agents, and mobile store advisors.

Meanwhile, LG Uplus's AI solution 'Ixio' and the 'work agent' based on Ixigen will also be featured in the AI-related report published by GSMA ahead of MWC25. The report is expected to include details on Ixio's AI call response, real-time chat, voice phishing detection functions, and the work agent's network operation automation and deep learning-based maintenance.

Lee Hye-jin, Head of Technology Strategy under LG Uplus's CTO, said, "We decided to participate in the Red Team Challenge so that customers can use AI services with greater confidence and trust." She added, "We will continue to collaborate with LG AI Research to continuously advance Ixigen to equip it with global-level security features."
